MACHINE FOR PRESSING SOLES UPON SHOES AND PAD THEREFOR Patented Feb. 14, 1933 UNITED STATES PATENT OFFICE MILTON H. BALLARD, OF BEVERLY, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHINERY CORPORATION, OF PATERSON, NEW JERSEY, A. CORPORATION OF NEW JERSEY MACHINE FOR PRESSING SOLES UPON SHOES AND PAD THEREFOR Application fiIed AuguSt 27, 1929. Serial No. 888339.

This invention relates to machines for use in the manufacture of shoes and is illustrated herein as embodied in a machine for use in cement-attaching soles to shoes.

The modern revival of the long-known compo process of shoemaking, in which the outsoles of shoesare securedto the uppers by cement, has called for the development of improved machinery for pressing the soles forcibly against the uppers of the shoes and for maintaining the pressure while the cement is setting. An improved machine particularly adapted for use in this work is that disclosed in an application for Letters Patent of the United States, Serial No. 352,278, filed April 3, 1929, in the name of Sidney J. Finn. It is an object of the present invention to provide a still further improved'machine for this purpose.

In the manufacture of shoes in which cement is relied upon to the exclusion of stitching, metallic fastenings orpegs to secure the soles to the shoe uppers, in accordance with present day practice pyroxylin cement is applied to the roughened or scoured surfaces of the overlasted portion of the shoe upper and to the marginal portion of the attaching surface of the sole. This cement is allowed to dry, after which it is out with a suitable solvent, the sole is applied to the shoe, and the two pressed forcibly together and held under pressure until the cement sets sufficiently to hold the sole securely in place. With the cements now in use for this kind of work and under the usual conditions this takes a considerable time, ordinarily minutes or thereabouts. From this it follows that each operator must be supplied with a large number of presse'r units, which may be permanent parts of a pressure-applying machine as in the cement sole attaching machines of the ivell-known Ferris-wheel type, or which may be separate from or separable from the pressure-applying machine, as in tie machine set forth in the Firm applica tion referred to in which each of the presser units consists of a so-called pad box comprising, as illustrated therein, a hollow vessel containing liquid and. made of distortable material such as rubber, confining means for said vessel formed and arranged to expose one wall of the vessel for the reception I after the operation of the deforming means,

so that the pad box and the shoe can be removed bodily from the machineto a storage place while the cement sets.

In view of the foregoing, a feature of the present invention comprises automaticallyactuated mechanism for holding a movable pressure-applying member of a fluid-containing pad member, the walls of which are of distortable material, in pressure-applying position. In accordance with another feature of the invention, the displaceable pressureapplying member, as illustrated, is, pivoted to the wall of the vessel and when displaced inwardly toward the wall of the vessel thereby dilates or distends a sole-receiving wall of the vessel, causing that wall to be pressed forcibly against the sole of a shoe to hold the sole in close contact with the shoe while the cement by which the sole is to be attached to the shoe is setting. A preferred form of the mechanism for holding the displaceable pressure-applying mechanism in position comprises, as illustrated herein, a curved wedge or cam member engaging a roll or other suitable part carried by the displace able member and automatically actuated to contact with said part by pivotal movement of the wedge or cam member, so that the latter will hold the displaceable pressure-applying member in any pressure-applying position to which it may be moved.

The means for resisting the thrust caused by the sole-applying pressure in machines of this character preferably, and as illustrated in the above-mentioned Finn application, comprises an abutment engaging the cone of the last and a toe rest engaging the forepart of the shoe upper. These members in the machine disclosed in the Finn application are moved into engagement with the shoe and last after the shoe is properly positioned relatively to the sole and are used to apply preliminary ressure before final pressure is applied by istortion of the pad member. In accordance with another feature of the present invention the means for moving these thrust-receiving members into engagement with the shoe and the lastinclude an adjustable connection and mechanism for adusting said connection to vary the relative extent of the movement imparted to and"the force exerted by the two members. This enables the operator' to control the application of the preliminary pressure in such a mannerthat he can in every instance cause the preliminary pressure to press both ends of the shoe firmly into contact with the sole and topress both ends of the sole firmly against the pad, regardless of variations in the size and shape of the shoes operated on.

In the illustrated machine, as in the machine set forth in the above-mentioned application, the sole and the shoe are positioned relatively to each other by gage members or feelers which are moved into and out of operative position at the toe and heel ends of t e shoe lengthwise of the sole of the shoe. Features of the present invention comprise improvements in the operating means these feelers or gage members, including an improved construction in which each set of gage members is moved ,to operative position by a weight mounted on a lever normally supported in inoperative position but manually releasable to render the weight ef fective to move the gage member to operative position. In accordance with a further feature of the invention power-operated means are provided for raising the weightsv to their normal inoperative position and for returning a treadle, displaced to release the weights and thereby to render them operative, to its inoperative position.

.Still another featurerelates to the provision of means by which the preliminary clamping pressure is maintained substantially uniform per unit area regardless of the sizes of the difi'erent'shoes operated upon. In accordance with this feature, and as illustrated herein, the mechanism for moving the last and shoe engaging members to apply the preliminary pressure includes a treadle lever and connections thereto of such a nature that the mechanical advantage of the lever system including the treadle is greater when the treadle is in the position which it occupies when applying preliminary pressure to a large shoe than when in the position it occupies when applying pressure to a small shoe.

While the invention is illustrated herein for as embodied ina machine developed fori use in' cement-attaching soles to shoes it should be noted that in various of its aspects it is not limited to embodiment in such a machine. Obviously, in various of its aspects it is adapted for use in machines of other types and machines for performing other operations, for example sole laying or direct pressure leveling as performed in the manufacture of shoes'the soles of which are permanently attached by stitching or other fastenmgs.

With the above and other objects and features in view the invention will now be described with respect to the accompanying drawings and pointed out in the claims.

The illustrated machine is provided with a frame comprising a table 20 (Figs. 1 to 4. inclusive) supported 'by legs 22 and arranged to receive a pad box 24 (Figs. 1 to 4, 8 and 9) by which a shoe 26 and a sole 28 may be held clamped forcibly together while cement, by which the sole is to be attached to the shoe, sets. The machine is provided with means for positioning the toe end of the shoe relatively to the sole before the clamping pressure is applied, as indicated generally The pad bow My improved pad box 24, details ofthe construction of which are best shown in Figs.

- 8, 9 and 10, comprises, as illustrated herein,

a hollow pad member 34 of heavy rubber about one quarter of an inch thick, approximately rectangular in plan view and having a normally flat bottom wall 36 and top-wall 38 reinforced with a sheet of textile fabric 40, such as duck, to prevent stretching of the wall 38 without substantially impairing its flexibility. The pad member 34 is contained in a box-like confining member 42, preferably an aluminum casting, having a door-like bottom member 44 pivoted at 46 and provided,

with a roll 48 at its end remote from the pivot 46 and arranged to engage with a wedge or cam surface 50 of a cam member 52 pivoted at 54 to the aluminumcasting 42 and rotatable about the pivot 54 by mechanism hereinafter described. When the cam member 52 is rotated to the full extent of its movement in the clockwise direction as viewed in Fig. 10 the roll 48 engages a portion of a surface 56 of the casting 42 on which surface the cam member 52 rests. The top surface of the pad-confining means comprises a steel plate 58 secured to the casting 42 by screws60 and provided with an opening 62 conforming generally to the outline of the sole of a shoe and sufficiently large to permit the sole of the largest shoe which is to be operated upon to be placed on the upper wall 38 of the pad member 34 without touching the plate 58. As best shown in Figs. 8 and 9, the top of the wall of the box-like member 42, the top wall of the rubber pad member 34 and the steel plate 58 conform in side elevation to each other andnappreximately to the longitudinal curvature of a last bottom thereby minimizing the deformation of the top wall 38 of the pad 34 necessary to bring the pad into contact with the entire area of the sole which is to be attached to the shoe.

The pad member 34 is provided with an opening 64, illustrated in Fig. 8 at its left hand end. through which it is filled with a fluid, preferably a liquid, for example water. The box-like member 42 is provided with an opening 66 in alinement with the opening 64, the pad member 34 being clamped to the wall of the box 42 by a closure 68 threaded to receive a pair of cap screws 70 which pass through holes formedon the end wall of the box 42. The closure 68is also provided with a threaded opening 72 through which water can be introducedinto the pad 34, after which the opening 72 is closed by a plug 74 having a taper thread. Water all the air in the pad is displaced by water, but the pad is maintained in a somewhat collapsed condition at the time the plug -74 is inserted so that a portion of the Wall of the pad can be displaced inwardly somewhat before substantial resistance is encountered.

The pad box posz'tz'om'uymetms The right-hand end of casting 42 of the pad box 24 is provided with a lug 76 arranged In filling the pad 34 Witlf to be received beneath a rigid arm 80 (Figs.

3 and 9) secured to the table 20 oft-he machine and the left-hand end of the casting 42 of the pad box is provided with a lug 82, arranged to be received beneath a'member 84 (Fig. 1) also carried by the table 20 to prevent the pad box from being moved upwardly when pressure is applied thereto by the engagement of a plunger 86 (Figs. 1 and 4) against a surface 88 of the pivoted bottom member 44, as will be more fully described hereinafter. The table 20 of the machine is also provided with a pair of stops 90, 92 F ig. 2) to limit the rearward movement of the pad box 24 when the pad box is placed on the table 20. To position the pad box 24 lengthwise on the table 20 with its right-hand end in engagement with the arm 80, an angle lever 94 is pivoted at the left-hand rear corner of i the position occupied by the pad box. The lever 94 is normally rocked somewhat in a clockwise direction from the position shown in Fig. 2 by a spring 98 anchored at one end to the lever 94 and at the other end to the table 20. The right-hand end of'the lever 94 is provided with an adjustable stop member, illustrated as a screw gaged by the rear of the pad box as the latter is positioned on the table 20, rearward move The part boa; yokes A pair of yokes 104 and 106 (best shown in Fig. 9) project upwardly from the casting 42 of the pad box 24 and transversely of the pad 34, serving to oppose and sustain the pressure by which the sole 28 is forced into engagement with the shoe 26 by pad member 34. The lower ends of the arms of the yoke- 104 are slidably mounted, as indicated at 108, on a rod 110 carried by a pair of lugs 112 projecting from the casting 42 to permit the 100, arranged to be enyoke 104 to be moved somewhat lengthwise of the pad box 24 so that a toe rest 114 carried by a plunger 116 having a bearing in the cross bar of the yoke-104 can be properly placed relatively to the shoe 26 notwithstanding variations in the size of the different shoes operated upon. A spring 118 bears at one end against a surface of the yoke 104 and at the other end against an enlarged head 120 of the plunger 116, tending to force the plunger upwardly. A spring-pressed pawl 122, pivoted to the yoke 104, cooperates with ratchet teeth 124 formed in-the plunger 116 to prevent upward movement of the plunger 116 except when the pawl 122 is withdrawn. l y

The yoke 106 is pivoted at'126 to the cast-, ing 42, thus being mounted for swinging movement to the right or in a clockwise direction, as viewed in Fig. 9. A pair of stops 128, 130serve to limit this swinging movement so that the yoke 106 cannot move to the left substantially beyond thevertical and cannot swing to the right beyond 45 or thereabouts. A'plunger'132 is carried by the yoke 106, being provided at its lower end with an enlargement 134 to engage the cone of a last and at its upper end with a head 136 between which and the yoke 106 a compression spring 138 is confined. A pawl 140 pivoted to theyoke 106 cooperates with a ratchet 142 formed on the plunger 132 to prevent upward"movement of the plunger 132 under the influence of the spring 138 except when the pawl 140 is withdrawn from the ratchet 142.

The operation of the pad bow.

In the operation of the machine a pad box 24 is placed on the table 20' and positioned as already described. The operator then places a sole on the top wall 38 of the pad 34 and positions a shoe relatively thereto with the aid of the positioning devices 30, 32. The yokes 104, 106 are positioned'so that the toe rest 114 carried by the plunger 116 engages the toe portion of the shoe-upper and the head 134 of the plunger 132' engages the cone of the last. Then the plungers 116, 132 are depressed by mechanism, which will hereinafter be described. and the positioning means 30. 32 withdrawn, leaving the shoe and the pad box in the condition shown in Fig. 9. Thus the shoe and sole are placed under a pressure which may be advantageously of the order of about twenty ounds to the square inch. The plunger 86 is then elevated by mechanism hereinafter described, thus rocking the pivoted member 44 about its piv- 0t 46 and distorting the bottom wall 36 of the pad member 34, as shown in Fig. 8. This dilates the upper surface38 of the pad member causing it to bulge slightly around the sole, as indicated at 144 in Fig. 8, pressing the sole forcibly against the shoe bottom by which it may e moved by the wedge 50 of the cam member 52 which is rotated in a counter-clockwise direction, as illustrated in Fig. 10, for that purpose.

If the form of the interior of the pad box casting 42 and the amount of liquid contained in the pad member 34 are such as to make it desirable, the upper surface of the pivoted member 44 may be provided with grooves 150 (Fig. 10) into which the bottom of the pad member 34 may settle-somewhat as the final pressure is applied, thus insuring, even in the case of a'large shoe, that the cam member 52 will be permitted to rotate sulficiently to bring the roll 48 away from the extreme end of. the wedge 50, which ortion of the wedge, in order to strengthen 1t, is preferably somewhat steeper than the remainder.

The preliminary pressure-applying means A bracket 160 (Figs. 3, 4 and 9) projects upwardly from the rear portion of the table pressure applying position to 20 and carries the fulcrums 162 of a pair of forwardly pro'ecting levers 164, 166 having at their ends for engagement with the tops of the plung ers 116, 132 when the levers 164, 166 are rocked downwardly. Each of the levers 164, 166 is provided with a tension spring 172 connected at one end to the extreme rear end of the lever and at the other end to the bracket 160 so that the forward ends of the levers 164, 166 are normally rocked upwardly, as shown in Fig. 3, away from the position normally occupied by plungers'116, 132

when the pawls 122, 140 are released. Ad-

justable stops illustrated as screws 174 (Fig.

at plates 168,170 arranged 4) carried by each of the levers 164, 166 engage with lugs 176 formed on the upper end of the bracket to limit the movement of the levers 164, 166 under the action of their springs 17 2.

The levers 164,166 are connected toward their forward ends by a rod 180 (Figs. 1, 2 and 9) the ends of which are loosely engaged,

. as shown at 182 (Fig. 9), in seats formed in those levers. The rod 180 is adjustably connected, as hereinafter described, to a lever 184, also fulcrumed to the bracket 160 at 162, and connected by a link (Figs. 3 and 4) fulcrumed at to the frame of the machine. Thus depression of 186 to a treadle 188 the sole into en agement with the shoe bot-' tom over thew hole area thereof regardless of the size or shape of the shoe, the connec-= tion between the lever 184 and the rod 180 is adjustable lengthwise of the rod 180, thereby varying the proportion of the pressure applied through the respective levers 164, 166 without, however, varying the positions of the pl'ungers 116 and 132 lengthwise of the shoe. Thus if the heel end of the shoe is reluctant to engage the sole then the connection between the link 186 and the rod 180 will be moved to the right, as viewed in Fig. 9, applying a greater proportion of the pressure to the heel end of the-shoe. As illustrated, these connections include a dog 192 adjustably carried by the lever 184 (Figs. 1, 2 and 9) the lower end of which is provided with a seat 194 engaging the rod 180, the dog being threaded to receive a relatively coarse screw 196 formed on or secured to a shaft 198 journalled in an upstanding portion of the lever 184 and provided with a hand wheel 200 by which it may be turned to adjust the dog 192 to the right or to the left as the case may be.

in order that the preliminary pressure per unit area may be maintained approximately uniform regardless of variations in the sizes of soles of difierent shoes, and to obviate the necessity of excessive movement of the treadle 188, differential connections are provided between the link 186 and the treadle 188. l his,

as best shown in Fig. 4, comprises a cam slot 204 formed in the treadle 188 and engaged by a roll 206 carried on a pin 208 projecting from the link 186. The form of the slot 204 is such that while the treadle 188 is being moved from its inoperative position to the position which it occupies when the plates 168, 170 of the levers 164, 166 contact with the upper ends of the pl'ungers 116, 132, the mechanical advantage of the treadle, considered as a lever, is relatively small so that the efiect on the levers 164, 166 of a small movement of the treadle 188 is relatively great, thereby rapidly bringing the parts of the machine into pressure-applying position.

the time the treadle 188 reaches the position which it occupies while a relatively large shoe with a relatively high last is being operated upon its mechanical advantage is relatively great so that the operator can apply a relatively large force to the shoe. As the treadle 188 is further depressed and moves to the position it occupies when a relatively small shoe mounted on a relatively low last is being operated on,the-mechanical advantage of the lever 188 diminishes so that the total pressure applied to the sole of the small shoe is less than that applied to the sole of a large shoe and the pressure per unit area is substantially the same in both cases. F or ward and rearward movement of the link 186 in response to pressure of the cam slot 204 on the roll 206 is controlled by a link 209 having its ends pivoted respectively to the lower end of the link 186 and to the shaft 190.

Means for applying the final pressure It will be remembered that the final pressure by which the sole 28 is clamped to the shoe bottom is provided by upward movement of the plunger 86 which slides in a hole in the table 20. For this purpose the lower end of the plunger 86 bears against a convex surface formed on the forward end of a lever 210 (Figs. 1 and 4) fulcrumed at 212 beneath the table 20 and pivoted at its. rear end to a downwardly extending link 214 which is in turn pivoted atits lower end at 215 to the intermediate portion of the forwardly extending arm 216 of a bell crank lever 218 tulcrumed at 220 on a bracket 224 extending downwardly from the table 20. Pivoted to the forward end of the lever arm 216 is a pair of short parallel links 226 (Fig. 4) the lower ends of which are pivoted to the upper end of a rod 228 on the lower end of which is a washer 230 positioned above a nut and lock nut 232 threaded on the lower end of the rod 228. A stifi compression spring 234 is seated on the washer 230 and surrounds the rod 228, its upper end serving to support a heavy weight 236 which is bored or cored to receive the spring 234, the rod 228 and the links 226. The upper end of the weight 236 is provided with a forwardly and rearward- 13; extending slot to receive the lever arm 216. The weight 236 tends, through the lever 218 and the link 214 to rock the lever 210 in a clockwise direction as viewed in Fig. 4, thus tending to elevate the plunger 86 to its pressure-applying position. This action, however, is normally prevented by mechanism, which will now be described, and is permitted to take place only when a controlling lever 238 is depressed. I

The machine is provided with a main power shaft 248 (Figs. 2, 3, 4 and 7) journalled in suitable bearings somewhat lower than and at the rear of the fulcrum 220 of the lever 218 and operated from a motor 250 through the gearing 252 and a suitable onerevoluiion clutch 254 controlled by the lever 238. Fast upon the shaft 248 is an eccentric 256 (Figs. 4 and 7) which engages andcooperates with a shoe 258 pivoted at 260 to a depending arm of the lever 218. These parts occupy the position shown in Fig. 4 when the machineisi at rest and serve to maintain the weight 236m its elevated position, permitting the plunger 86 to occupy its lower inoperative position in which its upper end is somewhat below the position occupiedby the surface 88 of the pad box 24, so that it will not interfere with the ositioning of the pad box on' the table 20 or t e removal of the pad box therefrom. When thecontrolling lever 238 is depressed, however, and theclutc 254 becomes operative,- the shaft 248 is retated through a single revolution in a counter-clockwise direction, as viewed in Fig. 4, so that the eccentric 256 permits the lever 218 to rock, also in a counter-clockwise direction, under the influence of the weight 236, thus rocking the lever 210 in a clockwise direction and forcing the'plunger 86 upwardlyagainst the surface 88 of the pad box 24 so that the ivoted bottom member 44 of the pad box is orced upwardly, distorting the pad member 34 and transmitting the final pressure of about sixty pounds to the square inch to the shoe bottom. The application of pressure by the weight 236 is gradual during the earlier part of the revolution of the shaft 248 by reason of the characteristic action of the co centric 256. As the shaft 248 completes its revolution the eccentric 256 returns to the position shown in Fig.4, lifting the weight 236 and thereby releasing the plunger 86 and allowinlg it to return to its inoperative osition.. efore the plunger 86 starts to rop, however, the cam member 52 is actuated automaticall to lock the pivoted member 44 of the pad ox 24 in its elevated position, thereby maintaining the premure on the shoe and sole afterthe plunger 86 drops. The mechanism by whichthis is done will now be described. I

The mechanism for opyemtmg the pressure maintaining device of the pad bow Journaled in suitable bearin s carried by the frame of the machine somew at above the shaft 248 is a rock shaft 262 (Figs. 3, 4 and 7) to which is secured a depending rock arm 264 carrying a roll 266 engaging the eccentric 256 at the rear thereof. Also secured to the shaft 262 is a downwardlyextending arm 268 bored to receive a plunger 270 seated upon a spring 272. The upper end of the Plunger 270 engages an arm 273 ofa bell crank lever 274 loose on the rock shaft 262 and having an upwardly extending arm 276 connected by a link 278 to a lever 280fulcrumed at 282 to the forward portion of the table 20 and having an upwardly extending arm pivoted at 284 (Fig. 3) to a finger 286 resting. upon an inclined surface of the table 20 and arranged, when the lever 280 is rocked in a clockwise direction as viewed in Fig. 3, to engage a lug 290 depending from the lower surface of an arm 294 forming a portion of the cam member 50. Thus when'the shaft 248 is rotated the lever 280 will be yieldingly rocked, first in a clockwise directiomand then back to its original position, the clockwise movement 65 causing the finger 286 to rotate the cam' member 52 to such an extent that the roll48 carried by the bottom member 44 of the pad box in the machine is engaged by the wedge or cam surface 50. \When the finger 286-returns to its inoperative position the cam member 52 is left in the extreme position to'which it has been moved and retains the pivoted member 44 in its pressure-applying position. The lever 274 is also provlded with a forwardly extending arm 296 connected bya spring 298 to a pin 300 (Fig. 4) carried at the rear ofthe table 20,'thereby rocking the shaft 262 in a clockwise direction as the eccentric 256 returns to its inoperative position. To insure the return of the finger 286 and the lever 280 to their normally inoperative positions, the shaft 262 is provided with an adjustable member, illustrated as a screw 302 (Fig. 7), arranged to engage the arm 273 in opposition to the plunger 270.

The shoe and sole-positioning means and the operating mechanism therefor The shoe and sole-positioning means 30 and 32 are mounted on a pair of brackets 310, 312 (Fig. 1) carried at the left and right-hand sides of the machine respectively. and adjustable about pivots 314, 316 by a pair of struts including the turn buckles 318, 320. The positioning mechanism 30 for the toe end of the shoe comprises two sets of feelers, as illustrated herein gage members (best shown in Fig. 2) carried by two pairs of arms 322, 423- mounted on a carriage 326 slidably mounted in ways formed in or carried by the bracket 310, the construction of this mechanism being as more fully disclosed in said Finn application Serial No. 352,278. The

' carriage 326 is connected by a cord or cable 328 to the forward end of a lever 330 (Fig. 1) 3 fulcrumed for swinging movement on the shaft 248' which projects outwardly from the frame of the machine for that purpose. Secured to the lever 330, and formed integrally therewith as herein illustrated, is a weight 332 which thus tends to move the carriage 326 to the right as viewed in Fig. 1, toward the position occupied bythe toe of a shoe upon the pad box 24. Similarly a carriage 336,

upon which the heel end positioning means I 32 are mounted, is, connected by a cord or cable 338 with a weight 340 carried by a lever 342 fulcrumed on the shaft 248 at the righthand side 'of the machine, thus tending to move the heel end positioning means 32 to the left toward the position occupied by the heel end of the shoe on the pad box 24.

In order to 0 rate the ositionin means 30, 32 against t e action 0? the weig ts 332, 340, the carriages 326, 336 are connected by cords or cables 344, 346 respectively, running over suitably arranged pulleys 350, 352, 354 and 358 (Fi 1) to rock arms 360, 362

. (Figs; 1 and-T 3) ast to the ends of the shaft' which servesalso as a fulcrum for the T treadle 188; The rock arm 362 is provided with a spring 364 anchored at the other end to a stationary member 366 secured to the; frame of the machine and thus tends to lift the rock arm 362.

The rock arm 362, when the machine is at rest, occupies the position shown in Fig. 3, being latched against upward movement by a latch member 368 (Figs. 3, 5 and 6) pivoted thereto by means of a club shaft 370 and engaging at its upper end a stationary stop 372 secured to the frame of the machine. Thus it will be seen that when the latch 368 is released and the rock arm permitted to rise, the weights 332, 340 willmove the shoe and sole and shoe-positioning devices 30, 32 into operative position, while when the rock arm 362 is depressed from the position shown in Fig. 6 to the position shown in Fig. 3, the weights 332, 340 will be elevated and the cords 344, 346 will return the shoe and sole-positioning devices 30, 32 to the positions in which they are shown in Fig. 1.

Details of the treadZe mechanism for reZeasing the shoe and sole positioning demoes The fulcrum 370 of the latch member 368 is secured by a set screw 354 to a foot member or pedal 316 (Figs. 3 and 5) which has an upwardly extending arm 378 pivotally connected to the forward end of a link 380 the rear end o1 which is formed with a slot 382 receiving pin 384 carried by the frame of the machine. Thus the rock arm 362 and the link 380 form substantially a parallel motion device but the slot 382 in the link 380 permits a certain amount of cloclrwise movement of the pedal member 37 6 from the position shown in Fig. 3. Later the treadle 376 is returned to the position shown in Fig. 3 b power-operated mechanism, and if it should happen that the operators foot is beneath the pedal 3T6 the latter will yield upwardly, owing to the presence of the slot 382, thus avoiding injury to the operators toot.

Loosely tnlcrumed on the shaft 370 is a secondary "foot member or pedal 386 overlying the pedal 37 6 and provided with a pin 388 5) connected by a spring 390 with a pin 392 projecting from the latch member 368. Thus it will be seen that when the operatorplaces his foot upon the pedals 386 and 37 6, those parts occupying the position shown in Fig. 3, and presses downwardly, he

will first tension'the sprin 390 and then will move the two pedals downwardly so that the latch 368 moves downwardly from the stop 372 and is swung forward (to the ri ht as viewed in Fig. 5) by the spring 390, s the operator lifts his foot the latch 368 moves upwardly beyond the end of the stop 37,2 and the weights 332, 340 become efiective to move the shoe and sole-positioning devices 30, 32 to the right and left respectively to their operative positions. When the operator thereafter removes his foot from the pedals 386,376 the latch member 368 is moved rearwardly by a spring 394 connected at one end we pin 396 carried by the latch member 368 and at the other end to a pin 398 projecting from the rock arm 362 and serving also as an anchorage for the (0rd '346.- The left-hand end of the pin 396, projecting from the latch member 368, serves. by engagement with a stop member 400 (Fig. 5) to prevent excessive rearward movement of the latch member 368.

In order to lift the weights 332, 340 after the shoe and sole have been positioned, thereby returning the shoe and sole positioning devices 30, 32 to their inoperative positions and at the same time returning the treadle mecchanism 362, 376 and 386 from the elevated position of Fig. 6 to the lowered inoperative position of Fig; 3, the rock arm 362 is connected by a link 402 with a rock arm 404 secured to the end of the rock shaft 262.

To insure that this may not take place prematurely the upper end of the link 402 is pro vided with a slot 406 engaging the pin 408 carried by the rock arm 404 so that the link 402 is not moved downwardly until the shaft 262 has partaken of a substantial portion of its rocking movement. Then, however, the pin 408 in its downward movement reaches the lower end of the slot 406 the link 402 is "forced downwardly, returning the treadle mechanism to the position shown in Fig. 3 so that the latch member 368 can be snapped under the stop 372 oy the spring 394.

The heel and positioning means and its opaeration The heel end shown in Fig. 2,

positioning means 32, best is not claimed herein since y it is the invention of said 1* inn and forms the riage 336 carries an end gage 410 (Fig. 2) as well as a pair of lever arms 412 carrying sole engaging members 414 and a pair of lever arms 416 carrying shoe positioning gage members 418, the arrangement being such, as more fully pointed out in said Finn application Serial No. gage 410 is brought to rest, as by engaging the end of a sole positioned upon the pad member 34, the carriage 336 will be brought to rest and will be latched against further mwement by the engagement of a latch member 420 with a ratchet 422. This prevents further forward movement of the carriage 336 and of the gage members carried thereby and permits movement of the sole'engaging members 414 toward each other and of the shoe engag ing members 418 toward-each other until the former engage the opposite edges of the sole and are positioned thereby. Afterthe. operator has placed the shoe upon the sole, un-

414,516, that when the end 'The operation 0 the maohz'ne after a shoe der the guidance-of the shoe gage members at the forward end, he depresses a hand lever 424 fulcrumed at 426 to the carriage 336, thus releasing a latch 428 from engagement with a cooperating member 430 carried by a lever 432 fulcrumed at'434 to the carriage 336. This simultaneously permits a lever 438 fulcru'med at 438 to be swung in a counterclockwise direction, as viewed in Fig. 2, thereby withdrawing the end gage 410 by reason of the engagementof a pin 442 carried thereby with the lever.436, and permits a spring 444 to rock the lever 432 in :1 clockwis'e'direction, as viewed in Fig. 2, thereby moving the levers 416 of the shoe positioning gage members or feelers 418 carried thereby toward each other, through connections fully disclosed in said Finn application Serial No. 4114516, thus positioning the shoe upon the so e.

and sole za've been positioned After a sole and shoe, the contacting faces of which have been suitably coated with -cement, and the cement suitably cut with solvent, have been positioned in this manner, the operator brings the yokes 104, 106 into the desired position so that the toe rest 114 is above the forepart of the shoe and theplunger 132 is above the cone of the last and V stepsupon the treadle 188 thus applying the preliminary pressure. As he does this, and after suflicient pressure has been applied to prevent the shoe from slipping relatively to the sole, he moves a hand lever 450, which at that time extends further to the right than the position illustrated in Fig. 2, to the position illustrated in Fig. 2, thus withdrawing 'then slides the pad box 24 forwardly from V the table 20 of the machine, placing it, for

example, on a rack, and replacing it with another pad box.

After the shoe has remained under presi sure in the pad box until the sole-attaching cement has set the pressure will be released by striking a sharp blow upon the arm 294 of the cam member 52, or the cam member 52 may be swung by pressure upon a lever placed in a hole 295 formed in the arm 294 for that purpose. Then the pawls 122, 140 are pressed to release the plungers 116, 132,

so that the shoemay be removed from the pad box.

48. A machine for use in applying pressure to soles and shoes comprising a pad arranged to receive a sole and a shoe, means including a lever for applying preliminary pressure to hold the shoe and the sole in engagement prior to the application of the final pressure, and connections extending from the lever to the vicinity of the pad such that the lever as it is rocked has at first a relatively small mechaniv cal advantage which increases to a maximum when the lever is in the position it occupies when operating on a shoe on a large last and thereafter decreases as thelever reaches the position it occupies when operating on a shoe on a small last.

49. A machine for use in attaching soles to shoes comprising a pad arranged to receive a sole and a shoe to which the sole is to be attached, means for applying preliminary pressure to hold the shoe and the sole in engageshoe on a large last and thereafter decreases as the lever reaches the position it occupies when operating ona shoe on a small last.

50. A machine for use in cement-attaching soles to shoes having, in combination, a pad arranged to receive a sole and a shoe to which the sole is to be attached, and means for appling pressure to the last and shoe positioned on the pad comprising a lever, a connection for transmitting pressure from the'lever to the last, a treadle, and a link connected at one end to the lever and at the other end to the treadle by a connection constructed and arranged to cause the treadle as it is displaced from its inoperativeposition to have at first a relatively small mechanical advantage to bring the leverquickly into position for operating on a shoe on a large last and increasing to a maximum when the lever is in the pos1t1on it occupies when operating on a shoe on t 4. a large last and thereafter decreasing as the lever moves to the position it occupies when operating on a shoe on a small last.

51. A machine for use in cement-attaching soles to shoes comprising a pad arranged to receive a sole and a shoe to which the sole is to be attached, and means for applying pressure tothe last and shoe positioned on the pad comprlsmg a lever, a connection for transmitting pressure from the lever to the last, a treadle, and connections between the lever and the treadle comprising a link connected at one end to the lever and carrying near its other end a roll positioned in 'a slotformed in the treadle, the form of the slot being such that as the treadle is displaced from its in operative position it has at first a relatively small mechanical advantage which increases to a maximum when the lever is 1n the position it occupies when operating on a shoe on a large last, thereafter decreasing as the lever moves to the position it occupies when operating on a shoe on a small last.

52. A machine for use in cement-attaching soles to shoes comprising a pad arranged to receive a sole and a shoe to which the sole is to be attached, means for applying preliminary pressure to hold the shoe and the sole in engagement prior to the application of final pressure, said preliminary pressureapplying means including a lever provided with a slot, and connections extending from the slot to the vicinity of the pad, the form of the first part of the slot being such that the initial movement 'of the connections as the lever is displaced is large relatively to the displacement of the lever, thereby rapidly bringing the parts of the machine into pressure-applying position, the form of the next part of the slot being such that the movement of the connections relatively to the movement of the lever is thereafter small, thereby applying considerable pressure when the shoe being operated upon is on a large last, and the form of the final portion of the slot being such that the final portion of the movement of the lever has a greater efi'ect on the connections thanthe intermediate portion so that a lighter pressure is exerted if the shoe which is being operated upon is-on a small last whereby the pressure per unit area applied to the shoe is substantially the same regardless of the size of the shoe.

53. A machine for use in attaching soles to shoes having, in combination, a hollow vessel containing fluid, means confining the vessel constructed and arranged to expose a wall of the vessel for the reception of a sole and a shoe to which the sole is to be attached, said confining means including a pivoted member engaging the vessel and arranged to be displaced inwardly about its pivot to displace a portion of a wall of the vessel, thereby causing the exposed wall of the vessel to be pressed forcibly against the shoe bottom, and means for displacing said pivoted member inwardly about its pivot.
